X=9

Step-by-step explanation:

3x + 67 + 4x + 50 = 180

7x+117=180

7x=63

x=9

CHECK

3(9)+67+4(9)+50=180

27+67+36+50=180

180=180

Answer from: xoxomiaa1

m∠DBC = 86°

Step-by-step explanation:

Find the variable, x. First, combine like terms. Like terms are terms with the same amount of the same variable:

3x + 4x + 67 + 50 = 180

(7x) + (117) = 180

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis,

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

First, subtract 117 from both sides of the equation:

7x + 117 (-117) = 180 (-117)

7x = 180 - 117

7x = 63

Next, divide 7 from both sides of the equation:

(7x)/7 = (63)/7

x = 63/7 = 9

x = 9

Next, plug in 9 for x in the angle DBC:

m∠DBC = 4x + 50

= 4(9) + 50

= 36 + 50

= 86°

m∠DBC = 86°

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
